Abstract:
To rapidly identify the cross-contamination problems caused by the positive control in the process of mumps virus nucleic acid detection, a new mumps virus RNA positive control was developed in this study. Using the same primers and reaction conditions, the cross-contamination problems caused by the positive control could be readily identified by comparing the fragments lengths of the PCR products between the positive control and the samples. This new RNA positive control of mumps virus can be widely used in the diagnosis and genotyping of mumps virus as a better laboratory quality control.
Insights
A new mumps virus RNA positive control was developed to quickly detect cross-contamination during nucleic acid testing. Comparing PCR product fragment lengths aids in identifying issues, improving laboratory quality control for mumps virus diagnosis and genotyping.
